My 3DS works just fine with my Wi-Fi connection (tests show that I'm fully connected) and yet I can't get my Soul Silver to work with my Wi-Fi.
When I go into the game's wi-fi settings (old DS Operating System menu) I can't connect with my router. Apparently my security isn't compatible. Is there a reason the 3DS' Wi-Fi doesn't supersede Soul Silver's?
I believe that what doesn't kill you, simply makes you... stranger...
i own a 3ds and the way to play online in ds games are simple from your 3ds and go to system setting on 3ds home then internet settings then ds connections then click on an empty slot then access point then you should see your router number if not or it doesnt let you go to yor router setting on your computer and change for wpa to wep this may make you change the passwords of everything thats using the router after that just type in your new password and enjoy i know this because i had to do this with my belkin router

To fix this just change your router's security from WPA to WEP. I would give you a tutorial but I don't know what router you use. Just look up how to on Google, also make sure you enter the IP address and stuff manually as the DS games can't do it automatically. Hope I helped.
